I've yet to hear the actual recording which is nowhere online. There's also another version of transcript here
[link] with added Lumpur Radar not Lumpur Control or Subang Control (whatever). As far as I know Subang ARTCC was the last contact. MH370 either pilots calling locally "Em Ach three seven zero" just normal but not for SQ68 using "Ess Keu Six Eight."
Yep --
They are trying to make flight MH370 disappear for the second time by switching identifiers to MAS370 and Malaysian 370.
Wouldn't the call sign for MH370 be more like "Malaysian Hospitality" especially for a young co-pilot doing it by the books rather than just shortening it to "Malaysian"???
